The Study of Distribution for the Plants of Alien Species on Specific Islands Monitored by Ministry of Environment, South Korea

Abstract

This study was conducted to provide information on alien species to the specific islands monitored by Ministry of Environment in South Korea, based on the National Survey of Natural Environment of Islands from 2006 to 2020. In the study area, a total 54 taxa, consisting of 17 family, 45 genera, 53 species, one variety, were found. Among them, two species classified as Ecosystem-disturbing species, Humulus japonicus (H. japonicus) Siebold & Zucc. and Ambrosia artemisiifolia (A. artemisiifolia) Linnaeus were found. Alien plants were identified on 127 islands (49.4%), H. japonicus were found on 27 and A. artemisiifolia on six specific islands. The spatial status of alien flora on the specific islands monitored by Ministry of Environment in our data can be basic ecological information for the conservation and management of plant species diversity on the islands.
